BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent N 0. 403,466, dated May 14, 1889.

Application filed January 25, 1889- Serial No. 297,554. (No model.)

To all whom it may concern.-

Be it known that I, STERLING GLOVER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York,

have invented certain new and useful Improvements in Bottle-Stoppers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which [0 it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to that class of bottles and jars which have stoppers that can be easily placed in position in the neck of the bottle or removed, and which when in position form, with an interposed washer, a hermetio seal, making the bottle or jar on this account particularly suitable for holding aerated waters, beer, and other liquids or fermentable matter, as a portion of the contents may be drawn off and the rest kept for future use without injury.

My invention consists of certain improvements in existing forms of bottles, &c., and I will now proceed to definitely describe the manner in which I propose to carry out my 0 invention.

In the drawings, Figure 1 is an elevation of my improved bottle. Fig. 2 is a central vertical section of the upper portion of my improved bottle. Fig. 3 is a partial vertical sec- 3 5 tion taken in the line a; 00 of Fig. 1. Fig. 4 is a top plan view of the neck of the bottle with the stopper removed. Fig. 5 is a partial vertical section taken in the line y y of Fig. 2

with the stopper in position, and Figs. 6, 7,

and S are different views of the stopper.

Referring to the drawings, the stopper a which can be made of glass, metal, wood, or other suitable maierialis formed in one solid piece, on the principle of a locking-button, with the upper fingerdisk, a, the stem or shank a projecting downwardly from it and carrying at its lower end two lugs or projections, a a A washer, b, is fitted onto the stem of the stopper against the under face of the finger- 5o disk at. The bottle consists of the body portion 0 and the neck 0'. Upon the inner wall of the neck, and placed oppositely, are the inwardly-projecting ledges 0 0 After the stopper is introduced into the neck of the bottle, by turning the stopper one-qu arter way 5 5 round, the lugs a a of the stopper engage with the ledges c c in the neck of the bottle. The pressure of the parts upon the interposed washer-which may be of rubber, cork, leather, or the like-forms a hermetic seal.

The construction just outlined is substantially of an old form, and to thisI have added my important improvement, which makes it at once a perfect bottle for the purposes hereinbefore mentioned. In the old form, owing to the construction, the stopper was liable to slip and become detached from unavoidable jolting in transportation or handling, for if once started the pressure of'the gas Within the bottle would invariably complete the detachment. In order to avoid this serious difficulty and provide a perfect bottle, I have formed a central recess or indenture, 0 on the under side of each of the ledges o in the neck of the bottle, so that when the lugs a a on the stopper are turned a quarter-revolution they slip into these recesses, and thus effectually prevent the accidental displacement of the stopper, which can be easily removed when desired by applying pressure enough to throw the stopper down against the elastic washer sufliciently to effect a disengagement of the lugs from the recesses.

It is obvious that my invention is equally applicable to fruit-jars or other vessels constructed with the usual depression at the rim.

In a bottle, the combination, with the neck provided with inwardly projecting ledges upon its inner wall, such ledges being cen- 9o trally recessed upon their under surfaces, of the stopper having a shank and projecting lugs, all operating substantially as shown and described.

In testimony whereof I have signed my 5 name to this specification in the presence of two subscribing witnesses.

STERLING GLOVER.
